The Koran affirms that a group of Jews were changed by Allah into apes for not respecting the Sabbath.
First of all Abraham,Isaac and Jacob/Israel have never,never observed the Sabbath because Mosaic Law did not exist in their time.It is only with Moses that the Sabbath was made a holy day,it is part of the ten commandments.Therefore the incident in the Koran happened after the Jews left Egypt.
There was a lack of respect for the Sabbath
“And question them concerning the township which was bordering the sea, when they transgressed the Sabbath, when their fish came to them on the day of their Sabbath, swimming shorewards, but on the day they kept not Sabbath, they came not to them. Even so We were trying them for their ungodliness.
And when a certain nation of them said, “Why do you admonish a people God is about to destroy or to chastise with a terrible chastisement?” They said, “As an excuse to your Lord; and haply they will be godfearing.”"
Jews are turned into apes
“So, when they forgot that they were reminded of; We delivered those who were forbidding wickedness, and We seized the evildoers with evil chastisement for their ungodliness.And when they turned in disdain from that forbidding We said to them, “Be you apes, miserably slinking!”"
A reference to the establissment of Mosaic Law,which has the Sabbath as a holy day
“And when We took compact(Note:the alliance of Mosaic Law) with you, and raised above you the Mount (Note:about Mount Sinai): “Take forcefully what We have given you, and remember what is in it; haply you will be godfearing.”
Some Jews were changed into apes
“Then you turned away thereafter, and but for the bounty and mercy of God towards you, you had been of the losers.
And well you know there were those among you that transgressed the Sabbath, and We said to them, “Be you apes, miserably slinking!”
And We made it a punishment exemplary for all the former times and for the latter, and an admonition to such as are godfearing.”
Jews and possibly Christians also were changed by Allah,not only into Apes but also into Pigs
“Say: “People of the Book (Note:of the Bible)
do you blame us for any other cause than that we believe in God, and what has been sent down to us, and what was sent down before, and that most of you are ungodly?”
Say: “Will I tell you of a recompense with God, worse than that? Whoever God has cursed, and with who He is wroth, and made some of them apes and swine, and worshippers of idols, they are worse situated, and have gone further astray from the right way.”"
The Logical Consequence
We have the following situation:
1.There are apes and pigs that exist today.
2.Some Jews were changed by Allah into apes and pigs more than 3,000 years ago.
3.Those same apes and pigs,who before were Jews,have in turn had descendants,other pigs and apes.By logic,there are millions of apes and pigs in the world that are the descendants of Jews.
